My present invention relates to improveover during its axial movement onto and of ments in wheels, and more particularly to from the felly band. Wheels having demountable rims, and has for v It willbe noted, as best shown in Fig. 2, its object to improve the same in the several that the surface 10 is much steeper than the particulars hereinafter noted. surface 11 so that the surfaces 10 and 12 do $0 T o the above end, the invention consists not engage until the demountable rim 14 is of the novel devices and combinations of desubstantially fullyon the felly band 9, therevices hereinafter described and defined in by'making it extremely easy to apply the the xclaimsl demo'untable rim 14 to the felly band 9 or In the accompanying drawings, which remove the same therefrom.

Cap 27. 95 The inner edgeportion of the felly band9 is" To permit the pneumatic tire to be apbent radially outward, and the outer edge plied to or removed from a demountable portion thereof is bent slightly radially inrim 14 by an axial movement in respect. to ward to afford oblique retaining or stop surthe felly band 9 and to permit said tire faces 10 and 11, respectively, and arranged and rim to be applied' to the felly band 9 100 to be engaged by reversel'y formed oblique or removed therefrom by a like movement, surfaces 12 and 13respectively, on ,a fdethe demountable rim 14 and felly band 9 mountable rim 14. Said rim, between its and felly 8 are provided with coincident surfaces 12 and 13, is circumferentially chanseatsA 28 and 29, respectively, in the form of A neled at 15 to remove surplus stock and to 'transverse channels, the outerv ends of which 105 cause said rim to be supported-on the felly vare open. The seat 28 is formed by pressband 9 only at its surfaces 10 and 11. Pref? ing the demountable rim 14 radially inerably, the felly bandv9`, between its surfaces fward, and the seat 29 is formed by forming K '10 and 11, is slightly inclined inward so the a notch 3() in the felly band 9 and pressing demountable rim 14 will move freely therethe felly 8 radially inward. The seat 28 ex- 110 to hold said valve stem inthe seat 28.

tends into the seat 29 with freedom for sliding movement. transversely with the wheel. The outer edge portion of the felly band 9 is transversely notched to afford a gap 31, and which gap extends through the channel 16 and to the open outer ends of the seats-28 and 29 to receive the outer end of the valve stem 24 and its cap 27.

Both the lock ring 17 and demountable flange 19 have sufficient spring tension to tightly contract in the channels 16 and 21, respectively, and to remove the same therefrom it is only necessary to spring their ends apart to circumgferentially expand said lock ring and flange. To positively cir- -cumferentially contract the lock ring 17 in the channel 16, there is provided a coupling sleeve or nut 32 having right and left-hand screw-threaded engagement with 4the projecting studs 33 on the ends of said lock ring.

and 3 that the demountable flange 19 extends outward of the respective edge of the demountable rim 14, and that the channels `16 and 21 are wider than the lock ring 17 and rib'20, respectively, and that said lock ring. 17 directly engages the demountable flange 19 and is out of engagement with the respective edge of the demountable rim 14;

The lock ring 17 is provided with an outer circumferentially extended shoulder 34 which rests on the outer edge of the channel 16 with a knife-edge engagement. The inner4` surface of the lock ring 17 has engagement with the demountable flange 19 radially outward from its shoulder 34 and is out of engagement with the.bottomy of the channel 16 so that, under the contrae tion of the lock ring 17, the same will move radially inward and thereby press the demountable flange v,19 inward against the tire casing 22. The tire casing y22 rests on the rib 20 and thereby holds the same in its channell 21 against circumferential expansion. A seat 35 is formed in the demountable rim 14 at the inner end of the seat 28 to receive the collar 26 and thereby position the valve stem 24 and hold the same,in its seat 28. The 'cap 27 engages the outer` edge of the demountable rim 14 and, together with the lock-ring 17, vcompletely closes the open-outer ends of the seats 28 and 29.

In mounting the tire on the rim 14 the demountable'flange 19 is first removed and said tire placed on the rim 14 by a true` axial movement which carries its angle valve stem 24 into its-seat 28, and at the completion of the movement of the tire onto the rim 14, the valve stem shoulder 26 enters its seat. 35 and is thereby positioned The demountable flange 19 4is next circumferentially expanded by drawing its ends apart. to permit the same to be placed in the chant will be noted by reference to Figs. 2'

i arrangement.

nel 21. Aften the tire is inflated, the same securely holds the demountable flange 19 von the rim 14 by its overlapping engagement with the rib 20 which holds the same in its 'channel 21,`thus locking the several parts assembled which permit the tire to be carried as a spare.

The rim 14 and tire mounted thereon are then placed-on the felly band 9 by a 19 on said rim. l

-Ais previously stated, the interlocking seats 28 and 29 prevent circumferential movement of the rim 14 on the felly band 9, and to further prevent suchnmovement there is formed on the surface 12 of said rim a rounded lug36 arranged to enter a seat 37 in the surface 10 of the felly band 9. While only vone lug 36 and the seat 37 therefor is shown, it is ofcourse understood y that a plurality'of Said lugs and seats'may be provided in circumferentially spaced 95 Referring now to Fig. 6, thenconstruction isthe same as that shown in the other fig ures with the exception that the demountable flange 19 is provlded with an outer rib 38 which extends between the outer edge of the demountable 4rim 14', and the lock ring 17, and is clamped against the rim 14 by said lock ring. The other parts shown inlFig. 6 are indicated by prime numbers which correspond to like parts in the other'figures.

Wha-t I claim is:

1.. The combinationwith an annular member', of a vdemountable rimY on the annular member and havinga demountable flange, said demountable rim extending between the annular member and demountable flange and single lock ring having'separable interlocking engagement with the annular member and arranged to independently hold the demountable rim on the annular member and the demountable flange on the demount! able rim.

2. The combination with an annular member having a circumferential channel, of a demountable rim on the annular lmember and having a circumferential channel, a circumferentially expansible demountable flange mounted in said channel, and a single lock ring mounted in the channel in said "125.

annular member and arranged to hold the demountable rim onx the annular member 3. The combination with an annular member having a circumferential channel, of a demountable rim on the annular member and having a circumferential channel` a circumerentially eXp-ansible demountable flange mounted in said channel, and a single lock ring mounted in the channel in saidl annular member and arranged tov hold the demountable rim on the annular member and the demountable flange against axial removal from the Idemountable rim7 said demountable flange being arranged to be held against circumferential expansion by an inflated tire on said rim.

4. The combination with an annular member having a circumferential channel, of a demountable rim on the annular memberand having a circumferential channel and a circiimferentially expansible demountable flange, said flange having a rib extending into the channel in the demountable rim, and a single lock ring mounted in the channel in the annular member and arranged to hold the demountable rim on the annular member and the demountable flange against axial removal from the demountable rim, said rib being loose in the channel in the demountable rim to permit a limited axial movement of the demountable flange on the demountable rim, whereby the pressure of an inflated tire on the demountable rim tends to move the demountable flange against the lock `ring and into its outermost position on the deinountable run.

o. .lhe combination with an annular member having a circumferential. channel, of a demountable rim on the annular member and having a demountable flange, and a circumf'erentially adjustable lock ring mounted in said channel for slight axial adjustment and having a shoulder resting on the` -annuiar member outward of its channel and supporting the lock ring for lslight radial movement in reffpect to the annular memben said lock ring being arranged to radially overlap the demountable rim and the demountable vflange for direct engagement with both thereof to hold the demountable rim on the annular member and the demountablc flange on the demountable rim.

G. The combination with an annular member, ot' a deinountable rim on the annular member and having a lcmountable flange` and common locking means mounted on the annular member for lslight axial adjustment and radially overlapping the demountable rim and the denmuntable flange for direct engagement therewith to hold the dcmountable rim on the annular' rmember and the demountable llange on the demountable rim.

In testimony whereof I affix my signature.
